SPECIFICATION forming part of Letters Patent No; 591,036, dated October5, 1897. Application filed April 2, 1897. Serial No. 630,418. (Nomodel.)

To all lll/hom t mag/concern:

Be it known that I, MORITZ ErsNEn, a citizen of the United States, andaresident of New York city, in the county of New York and State ofNewYork, have invented certain new and useful Improvements inIncandescent Gas-Burners, of which the following is a specification.

My invention relates to the construction of burners for incandescentgas-lamps, and its objects are directed especially to the purpose ofpromoting the admixture of the gas and air supplied to the burner; towhich end it consists of certain novel features, including a hollowglobe, forming a gas and air mixing chamber, with lateral air-inletopenings in its lower part, a gas-supply nozzle connected to the bottomof the globe, a draft-tube connected to the top of the globe, anair-controlling valve encircling the lower part of the globe, withopenings adapted-to register with said air-inlet openings, and a ballsuspended in the center of the globe to form a deflecto'r of the mixedgas and air ascending through the mixing-chamber to the drafttube, andthence to the tip of the burner.

My invention is illustrated in the accompanying drawings, in which-Figure I represents a vertical central section of the burner embodyingthe same. Fig.

II represents a side elevation thereof, omitting the burner-tip and itsaccessories. Fig. III representsl a horizontal section of the burner,taken in the plane between two sections constituting the globe ormixing-,chamber. Fig. IV represents a partial side view and partialvertical section of the burner with the ball-deflector in positiontherein. Fig. V represents a horizontal section corresponding to Fig.III, including the ball-defiector.

Similar letters of reference indicate similar parts.

The letters A B indicate two hemispherical sections composing the globe,which constitutes the gas and air mixing chamber of the burner.

The letter C indicates the lateral air-inlet openings of the globe, thelocation of which is at the lower part thereof;

D indicates the air-controllingvalve, which is fitted on and encirclesthe lower part of the globe opposite toits said air-inlet openings andwhich has openings c at suitable points for adapting the same toregister with the openings of the globe.

' The letter F indicates the gas-supply nozzle, which is connected tothe lower part of the globe, and G the draft-tube, which is connected tothe top of the globe, said drafttube being surmounted by the tip S,forming the burner proper. i

The letter II indicates the ball-deector, (see Figs. -IV and V,) whichis suspended in the center of the globe A B by means of wires I, theends of which are fitted in the horizontal joint between the sections ofthe globe.

In the use of the burner the gas and air are mixed in the chamber formedby the globesections A B, and thence ascend through the draft-tube G tothe tip S, which is the point of combustion, and it will be readilyunderstood that by reason of the globular shape of the miXing-chambeigaswell as the ball-deflector I-I, a very effective admixture of the gasand air is obtained. It should be remarked that instead of a sphericalshape the globe A B may be of elliptical or other approximate shape, oneand the important feature thereof and of its interiorly-arrangedballdeflector being the interposition of these parts between thegas-supply nozzle F and the draft-tube G, leading to the tip of theburner.

The valve D is movable horizontally on that part of the globe which itencircles and may be provided withl a knob 0, Fig. II, to facilitate itsadjustment, and in order to arrest any impurities in the gas fromascending to the tip of the burner the draft-tube may be provided with asieve or strainer 'a at or about its junction with the mixing-chamber.

That I claim as my invention, and desire to secure by Letters Patent, is

In an incandescent gasburner, a hollow globe forming a gas and airmixing chamber constructed in two horizontally-divided sections, withlateral air-inlet openings in its lower part, a gas-supply nozzleconnected to the bottom of the globe, a draft-tube connected to the topof the globe, an air-controlling valve encircling the lower part of theglobe with openings adapted to -register with Signed at New York city,in the county of said air-inlet openings thereof, a ball suspended inthe center of the globe, forming a. da-y of March, A. D. 1897. defleotorof the mixed gas and air, and the MORITZ EISNER. ball-supporting Wirestted in the joint be* Witnesses:
